Description

The utility model relates to equipment for the preparation of municipal solid waste for sorting and processing and can be used to break bags and sacks with these wastes before separating them at the beginning of the sorting process.

The Matthissen SRIII-K4 Packet Breaker is known in the art (htttps: //www.bagsplitter.com/ru/ Garbage-Packet Breaker /). The specified known device is a close analogue of the claimed utility model and is taken as a prototype. This known device is shown in Fig. 1, Fig. 2, Fig. 3. In Fig. 1, a known bag breaker is shown assembled, in Fig. 2 it is shown without a hopper, figure 3 shows a view of a known bag breaker from the inside in a three-dimensional projection.

The packet breaker, taken as a prototype, consists of a frame (1), a hopper (2) fixed on it, and an electric drive with a gearbox (3). A drum (6) with feed knives (9) is fixed on the axis of the electric drive with a gearbox, while the specified drum rotates counterclockwise during operation of the breaker. Above the drum (6) with the feed knives (9), on the bed (1), there is a hydraulic drive (7), which can change the position of the comb with bursting knives (8), also fixed on the bed above the drum (6) with the feed knives (9 ). Damping devices (5) are installed between the bed (1) and the comb with bursting knives (8). A hydraulic pump (4) is located in the lower part of the bed, which ensures the operation of the hydraulic drive (7) by changing the position of the comb with bursting knives (8).

The operation of the known device is illustrated in FIG. 4. Packages with solid municipal waste are fed to a drum (6) with feed knives (9), rotating counterclockwise. The supplied bags with solid municipal waste are captured by the feeding knives (9) of the drum (6) and advance between the drum (6) and the comb with bursting knives (8), which break the bags with solid municipal waste, after which they can be fed for further sorting or recycling. Using a hydraulic pump (4) and a hydraulic drive (7), it is possible to adjust the distance between the comb with bursting knives (8) and the drum (6) with feeding knives (9), which depends on the size of the bags and the density of solid municipal waste. At increased loads on the comb with bursting knives (8) (for example, instead of a bag with solid municipal waste, any large object has fallen), the damping device (5) begins to work, which softens the impacts and prevents deformation of the elements of the comb with bursting knives (8).

The disadvantage of the known device is that during operation on the drum (6) with the feeding knives (9), the fibrous fraction of the waste is wound, mainly this is a stretch film, cash register tape, cables, pieces of rope, etc. This circumstance forces the drum to be periodically cleaned with the breaker stopping and its partial disassembly, which is a rather laborious operation.

The technical result of the claimed utility model is to increase the cleaning efficiency of the drum (6) with the feeding knives (9).

To achieve the claimed result, the known device, consisting of a bed, a hopper, a hydraulic pump, an electric drive with a gearbox, on the axis of which a drum with feeding knives is fixed, combs with bursting knives with a hydraulic drive and damping devices, additionally introduced a comb with cleaning knives (10, Fig. 5) and a hydraulically driven comb with cleaning knives (11, Fig. 5), placed in the hopper (2, Fig. 5).

The specified comb (10) has two positions - upper and lower, and its movement from one position to another is carried out using a hydraulic drive (11), which, like the hydraulic drive of the comb with bursting knives (8), is connected to a hydraulic pump (4) ... In this case, the comb knives with the cleaning knives (10) in the lower position and the feeding knives (9) of the drum (6) are staggered relative to each other (Fig. 6).

The operation of the inventive device is shown in FIG. 7 and FIG. 8. In the operating mode of the breaker (Fig. 7), the comb with the cleaning knives (10) is in the upper position, and the packet breaker operates normally, like the known device taken as a prototype. In case of excessive winding of the fibrous fraction on the drum with feeding knives, the operator switches the breaker to the “Cleaning” mode, in which the supply of bags with solid municipal waste stops, the comb with cleaning knives (10) is lowered by means of a hydraulic drive (11) to the lower position (Fig. . 8), and the drum (6) with the feeding knives (9) begins to rotate clockwise, while the cleaning knives cut off the fibrous fraction wound in the process of operation. Upon completion of cleaning the drum (6), the comb with the cleaning knives (10) is moved to the upper position, the drum (6) with the feeding knives (9) is rotated counterclockwise, and the supply of bags with solid municipal waste is resumed.

Thus, due to the introduction of a comb with cleaning knives (10) with a hydraulic drive (11) into the known burst of bags for solid municipal waste, the efficiency of cleaning the drum (6) with the feeding knives from the fibrous fraction wound on it during operation is increased.

Claims (1)

A bag breaker for solid municipal waste with an automatic drum cleaning system, consisting of a frame, a hopper, a hydraulic pump, an electric drive with a gearbox, on the axis of which a drum with feeding knives is fixed, combs with breaking knives with a hydraulic drive and damping devices, characterized in that with on the inside of the hopper there is a comb with cleaning knives with a hydraulic drive, while the specified comb with cleaning knives has two positions - the upper one, in which the drum with the feed knives rotates counterclockwise, and the lower one, in which the cleaning knives of the combs with the cleaning knives are located in a checkerboard order with respect to the feed knives of the feed knife drum, and the feed knife drum rotates clockwise.
